Spark plugs
Well I am not finding any particular answers and the stuff I read a while ago I cannot seem to find anymore.
I picked up some Denso IT20 plugs for my truck. I read a while ago these were GTG but I am seeing a vastly different gap between these and the plugs that come up on auto part store websites. Most plugs are between .54 and .55 and one Motorcraft is .41.
These IT20's are at .35. Is it because the electrodes are so small at .4mm that they gapped them that way?
The vendor I bought them from said they work for the 4.6 engine code W, which is the 2V. Will I be GTG or will I need to re-gap? They have the same reach, seat type and thread as all Motorcraft OEM's and OE replacements

These engines call for these plugs to be gapped at .054, .035 seems awfully close to me. I don't think your vendor knows what he's talking about. I would have put Motorcraft plugs in it gapped at .054 and forgot about it.
